The story follows the daily adventures of the four Mapui sisters: Ina, the eldest and most responsible; Mina, the stylish one; Mynah, the brainy bookworm; and Mo, the energetic youngest sibling. While they are all very different, they earn the title of "Super Siblings" not because they have capes or flying powers, but because of their incredible teamwork and the way they have each other's backs—even when they are driving each other crazy!
